Not worth the money

Personally I have never been able to get this app to work effectively. The sleep cycle app is absolutely wonderful, but I dont feel power nap utilizes as much technology as it could. I keep attempting to use it (following the instructions closely) but each time the alarm fails to go off and I wind up sleeping for two hours. I!d recommend spending your money on a cup of coffee instead.
